CEOS_EXTRA provides a dataset documenting the historical and recent range expansion of the pileated woodpecker (Dryocopus pileatus) in North Dakota. The data synthesizes natural history writings and sightings from the 1800s to the late 1900s, supporting evidence of population establishment in areas like the Turtle Mountains and Sheyenne River. The dataset's purpose is to present information confirming the species' westward movement.
Use Cases
- Modeling species range expansion over time based on historical sighting records.
- Analyzing habitat suitability and colonization patterns in regions like the Agassiz Lake Plain and Turtle Mountains.
- Studying the impact of historical documentation gaps on perceived species presence.
- Tracking recent population establishment in specific areas like the Sheyenne National Grassland and Devils Lake.
Strengths
- Focuses on a specific, well-documented species (Dryocopus pileatus) with a clear historical narrative.
- Covers a long temporal range, from the 1800s to the late 1900s, for tracking change.
- Provides specific geographical references, including the Agassiz Lake Plain, Turtle Mountains, and Sheyenne River.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Last update date is unknown; freshness unverified.
